Jazz from Hell is an instrumental album whose selections were all composed and recorded by American musician Frank Zappa. It was released on November 15, 1986, by Barking Pumpkin Records on vinyl and cassette, and in 1987 by Rykodisc on CD.

Civilization Phaze III is the sixty-third album by Frank Zappa, released posthumously as a double album on October 31, 1994. It was the first studio album of new material from Zappa since 1986's Jazz from Hell. The album marks the third part of a conceptual continuity that started with We're Only in It for the Money (1968), with the second part being a re-edited version of Zappa's 1967 album Lumpy Gravy. Zappa described the album as a "two-act opera", but in lieu of traditional recitatives and arias, it alternates brief spoken word passages with musical numbers created on a Synclavier using a combination of sampled and synthesized sounds. Much of the sampled material in the second half of the album was originally recorded by Ensemble Modern and other musicians to Zappa's specifications.
